- New York, in the county and State of New York, have invented certain new and useful Improvements in. Stitch Impression Machines, of which the following is a specilication.

My invention relates generally to machines for producing stitch impressions or indentations on the welt or the margin ofthe sole of a shoe, either to separate stitches therein or to simulate the appearance of stitches.

One object of the invention is to produce ay machine by which the curved portions of the welt or the sole margin, particularly at the tip of the toe, may beoperated on with greater facility and efficiency, and tol this end the machine is provided with a tool hav` i ing a working extremity or tooth of 1m,

proved form, and a feeding movement of novel character is imparted to the tool.

Another object of the invention is to-pro duce a machine by which the stitch impressions are impressed and burnished ata single operation, and to this end the machine is .constructed to impart both impressing and" burnishing movements to the tool or the work.

Other objects and features of the i1Lvention will be noted in connection withthe following description of the illustrated embodiment of the invention.

1n the accompanying drawings Figure l is a vertical median section yof a machine embodying the invention. Fig. 2 is a plan view of the machine with the cover and the work rest removed. Fig. 3 is a front eleva tion of the machine. Figs. 4 and 5 are a diagrammatic plan view and side elevation, respectively, illustrating, on an enlarged scale, the mode of operation of the tool.

The illustrated embodiment of the invention is a machine adapted particularly vfor producing imitation stitches or stitch impressions. The tool 1 has a shank 2 fixed in a socket 3 by means of a set-screw 4. The socket is formed in the front end of the tool carrier 5, which has the form of a shaft journaled in a sleeve 6. yNear its forward end the sleeve has a downwardly-projecting lug 7 by which it is pivotally mounted on a shaft 8 carried in the upper ends of two arms 9 project-ing upwardly from a sleeve 10. The sleeve l() is journaled on a shaft 11 which turns in bearings 12 on the base mem ber 13 of the machine. A The construction above described is/such that lateral rocking movements may be iinparted to the tool by turning the tool ca'rrier 5 in the sleeve 6, while the sleeve 6 may he moved longitudinally to advance or retract the tooland'tilted vertically upon the shaft 8 to move the tool vertically.

Thesleeve 6 forms part of a lever having rearward extensions 14 terminating in .ceccentric straps 15 which embrace eccentrics 1G by which the sleeve 16 is actuated. The ec' centrics 16 are mounted on a drive shaft 17 journaled in sleeves 18.011 the base 13 and connected, by a pulley 19, with a suitable source of power. Y

The sole of the shoe operated on is supported by a rotary work support 21 of ordinary form, which is journaled on an arm 22 projecting from a stem 23 sliding vertically in a sleeve 24- o n the base 13. A gib 25 engaging vertical slots inthe sleeve 2,4 ,pre-l vents rotation of the stem, and a roller 26 supports the inner' margin of the work support against the pressure of the tool. The work support is pressed upward by a spring 27 located in the sleeve 24 and adjustable by means of la threaded sleeve 28. A rod 29 ixed to the stem 23 passes loosely through the sleeve 28 and is provided with stop nuts 31 to engage the sleeve 28 and limitithe upward movement of the work support when no work is in the machine.v A nut 30 fixes the sleeve 23 in adjusted position. The rod 29 is perforated at 32 for connection with a suitable treadlek (not shown) by which the work support is drawndown to facilitate' the insertion of the work.

The upper surface of the work is normally pressed upwardly by the action of the spring 27 against a work rest 33 which bridges the tool 1 and has lower rounded work-engaging surfaces at either side thereof. The work rest is fixed to the frontof lthe cover 37, which incloses the actuating mechanism of the machine, by screws 34engaging lugs 36 on the work rest. The cover 37 is vsecured to the base by screws 41 engaging lugs 42 on the base.

Theoscillating movements of the tool carrier 5 in the sleeve 6 are caused by meclian tool a movement transverse to the tooth and of greater amplitude at the rear end tha at the front end of the tooth. t

2. A stitch-impression machine comprising a work support, a rotatable tool support, a tool mounted thereon and having an impression-forming tooth disposed at an angle with the axis of the tool support and with its forward end nearer theV axisthan its rear end, and means for imparting an intermittent partial rotation to the tool support and the tool. n

3. A stitch-impression machine comprising a work support, a rotatable tool support, a tool mounted thereon and having a working extremity provided with a plurality of impression-forming teeth and formed substantially as a segment of a toothed truncated cone with its small end forward, and means for imparting intermittent partial rotations to the tool support.

4. A stitch-impression machine comprising a work support, a tool, and means for moving the tool, in a plane substantial/ly perpendicular' to the surface of the work and to the direction of feed, through a continuous curved path toward and from the surface of the work and also along the surface to burnish the impressions.

A stitch-impression machine comprising a work support, a tool provided with an impression-forming tooth, and means for actuating the tool to move the tooth first toward the work transversely with respect to the surface thereof, to form a stitch impression, and then substantially in the plane of the work and in the direction of the length of the tool to cause the tool to have a sliding burnishing movement in the stitch impression.

G. A stitch-impression machine comprising a work support, a tool, and means for imparting to the tool first a movement toward and into contact with the work, and then a combined impression-forming and burnishing movement ina general retracting direction longitudinally with respect to the impressions.

7. A stitch-impression machine comprising a work support, a tool, and means for moving the tool first into contact with the work, then ret 1acting the tool along the sur-` face of the work longitudinally with respect to the impressions, and then moving the tool out of contact with the work.

8. A stitch-impression machine comprising a work support, a tool, and means for moving the tool in a plane substantially perpendicular to the surface of the work and the direction of feed in a substantially-elliptical path of which the minor axisv is substantially normal to the surface of the work.`

9. A stitch-impression machine comprising a work support, a tool, means for vibrating the tool into and out of contact with the surface of the work, and means for imparting a rolling movement to the tool, when it is in contact with the work about a center located above the plane of the work.

10. A stitch-impression machine comprising` a work support, a tool providedv with a pluralitybf impression-forming teeth, and means `for moving the tool to cause itsuc-` cessively to engage the work, perform aburnishing movement longitudinally with'rei spect to the impression, disengage the work,

advance through the space of one tooth, and

again engage the work and repeat the burnishing operation.
